The foundation of the entire online casino industry rests upon a mathematical algorithm known as an RNG.

Without this system, it would be impossible to guarantee that games are truly random and not rigged.

What Exactly is an RNG?

An RNG, or Random Number Generator, is a highly complex computer program that continuously spits out numbers.

When you press ‘spin’ on a slot or ‘deal’ in blackjack, the software grabs the very last number generated.

• The numbers correspond to specific outcomes on the reels or cards
• It is mathematically impossible to predict the next number in the sequence
• The generator does not possess a memory of past wins or losses

How Casinos Prove Their Software is Legitimate

To ensure player trust, legitimate casinos do not test their own RNG software; they use third-party agencies.

These independent auditors check the source code to guarantee that the house is not cheating the players.

Always verify that a casino displays a fairness certificate at the bottom of their homepage before depositing.
